METHOD AND SYSTEM FOR NETWORK PLANNING IN FIXED WIRELESS BACKHAUL NETWORKS

摘要

Systems and methods are disclosed for networking planning for fixed backhaul networks comprising a plurality of hubs, each serving one or more RBMs. The method comprises one or more of terrain pathloss (PL) and antenna gain prediction; network design comprising site association, hub dimensioning and pointing; and optimization of small cell (SC) deployment. PL prediction is based on correlation of user input parameters with reference use cases for channel models for each of downtown, urban, and suburban deployment scenarios. Rapid and effective network planning is achieved with limited input data, even in the absence of high resolution digital maps or building polygons, by selecting the channel model having a highest correlation with available environmental parameters. Optimization of network topology design, system design, and SC deployment, with both access link and backhaul link evaluation, is based on optimization of a sum-utility function across all links for feasible SC site locations.

1. A method for network planning for a fixed wireless backhaul network comprising a plurality of nodes, wherein each node comprises at least one hub module (HM) at each macro-cell site, and each hub module serves a set of remote backhaul modules (RBMs) through hub-RBM radio links, each RBM being located at a small cell (SC) site, and wherein the method comprises one or more of:
a) terrain pathloss (PL) and antenna gain prediction; b) network design and system design comprising site association, hub dimensioning and pointing; c) optimization of small cell deployment; and wherein performing Terrain PL prediction comprises selecting one of a set of reference use cases comprising channel models for each of downtown, urban and suburban use case scenarios, and performing PL prediction and other network planning steps based on user input, and estimated inputs for other parameters based on the selected channel model.
